@XH/(mesmo Will be lclosed by the thermostat 32v and the two solendidsivill beenergized. VThis will result in their cores Aand 4=5being drawn up, permitting gas to flow up throughthe 5 pipe 36 through the valve-body 39 and-the burner nozzle 40. ythe saine time the` valve 13 will be turnedV from its normal horizontal; position, across the pipe 5 to the `vertical position shown in Fig. l2 so as to loper'mit-a flow of airthrough the pipey 9 up- "Aivard through the tube 5 4of the -middle section, around the nozzle 40 Linto thefmixing chamber. .f Y i The'gas burner is formed of arectangular 15.-'cap k50 'corrugated transversely to the radiya'tor, as shoivnin Fig. l. The upper'portions of these corrugations'are formed With narrow" slits '52 through which the mixed 'airfand gas can pass. Thisfcap' 50 is Lheld in zo'fposition on the mixing chamber 53 of the burner by means of screvvs 54. Securedljagainst the sides of this capbyV means of Y-s'creWs 55 are thezsiderplate's l56, which have flanges 57 and lugs 58 to position thecurved 25.p'la'te 159. rExtending ,around ythe vouter wedges ofi-these plates 56A and down to the front.` andrear,'edge ofthe mixing: chamber 53,: as vshown in Fig." 2, is a cover plate 60.

@This insures an air chamber around the 30 curved plate E39-'Which becomes very hot and j would rscorch4 any animal and .vegetable mat- -Vter' touching it.
